VajkyPOS

The Vajky Point Of Sale system was developed to rewrite an existing, not-so-beautiful cash register software. Today, the goal is to develop a completely new and user-friendly, yet efficient cash register software. The software will be designed to meet the requirements of the National Tax and Customs Administration and other standards.

The program was written in Python, using the Pygame module, that can be compiled into an EXE file, and can run on windows computers without any external installations. The free download will be available soon, along with the source code on GitHub.

About the software

The software contains many features to achieve maximum efficiency, and provides full customization to meet the needs of every entrepreneur and their product list. The program stores the products, their types, and prices in an external file. It also allows for menu options and category changes. Planned features include receipt printing, kiosk mode, card terminal connection, synchronization of orders and products with a server, customization of product components, and user login.

Design and configuration

The software draws the buttons and labels on the screen based on predefined appearance standards, which may result in improper display on some screen sizes, or the inability to resize them due to their placement. As a solution, we have created a starter program that preconfigures the screen size to use the best possible settings. If our users require any special resizing, we will expand the resizing options with a new update.

How does It work?

The installation of the program will include a pre-built product list, which can help in creating a custom product list. The information is stored in a JSON file, which is easily modifiable. Some basic functions:

Category buttons (e.g. sauces, sandwiches, sweets, menus...)
Button color, shape, fill, and text customization
Menu options
Item categories: Drinks, sides, normal items
Customizing display settings.

Example structure for storing button data in a JSON file:
